Abstract
Official abstract text for this publication.
In an internal combustion engine that causes a predetermined gas flow in a combustion chamber, discharge plasma generated by a discharge device is caused to effectively absorb energy of an electromagnetic wave emitted from an electromagnetic wave emission device. At a time when a discharge operation and an emission operation are simultaneously performed so as to ignite a fuel air mixture, an emitting position of the electromagnetic wave on an antenna during the emission operation is located downstream of the discharge gap in a direction of the gas flow at the discharge gap so as to face toward the discharge plasma that has been drifted due to the gas flow.
First claim
Opening claim text (preview).
What is claimed is: 1. An internal combustion engine comprising: an internal combustion engine main body provided with an intake valve and an exhaust valve and configured to produce a predetermined gas flow from a side of the intake valve to a side of the exhaust valve in a combustion chamber; a discharge device that generates discharge plasma at a discharge gap located between the side of the intake valve and the side of the exhaust valve in the combustion chamber, the discharg…
